Hello and Welcome Ajldsi to the Do It Yourself Web Site and my Small Engine forum.

My assumption here is your going to replace the seal with the engine still mounted. You may be able to do this without removing the entire engine.

First thing would be to clean the entire area. Run the engine and verify the oil is in fact coming from the oil seal.

Althought there are special tools for removing an seal, I have to assume you do not have one. In that case, you can pry it out but do it carefully.

Once you have clear access to the seal, pry it out. Use caution. Do not use the engine cases surface as a leverage point soley. Spread the force out by using a piece of wood between the prying tool and the case.

To install a new seal you can place it into location and gently tap it to hold it in place. Then use a socket that fits the diameter of the ring and tap it into place until it is seated.

Be sure to fully clean the expossed crankshaft and oil it prior to both operations.

Regards and Good Luck,

After you verify the source of the leak, as Tom said, an alternative to prying is: punch a small hole in the seal between the crankshaft and the block. Take a small screw and screw it into the hole just enough to get a good hold of it. Be very careful not to let the screw scratch the crankshaft. Grab the screw with pliers and pull the seal out. Some seals are stubborn and the head of the screw makes a good contact point to pry it out with if you have to.
